Incredibly, on a Sunday, half the action is done with before the day's even begun for most of us. The day dawns with cycling, adventure treks and a heritage walk, and moves on with theatre, a craft bazaar, classical music and college flavour.
A campus festival that has almost everything, including an online game of terrorism, a guitar workshop and an under-water soccer game with robots. Get here or perish.
In all probability, its own neighbours don't know its a heritage site. Well the sight of a group of adrenaline junkies climbing on to it sure will alert them.
